The attribute would impose 64-bytes alignment that we do not
respect later because the whole structures (e.g. process/thread)
are allocated at 32bytes boundaries with kmalloc
These are however justified for performance reason as we do not want
them on same page cache line, so just accept slower performance for
UBSAN only

A signed integer cannot be shifted in a way that will flip the
sign bit; make such arguments unsigned to be safe

The original fujitsu code added a whole new ihk_mc_perfctr_stop_first
function, duplicating a lot of code - add a flag to existing function
instead.

Since interrupts are disabled on panic, linux cannot reset a
panic'd core when NMI are disabled (for e.g. mcreboot/mcstop)
Just always offline it, so linux can get it back

We need to separate the two because the heap of a PIE is created in
the area to which it is mapped.

user_start

system call that dereferences a NULL pointer fail

Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

A later version would probably want to check some mask for arm64...

In arm64, glibc-open of /dev/xpmem is hooked in sys_openat. This
commit adds xpmem_openat which is called by sys_openat.
This commit silently applies copy_from_user fix to sys_open as well.

these functions are more logical to keep together there as they depend
on each other.
Also add a comment about the __printf attribute, if we have a quiet
period it would be useful to enable and clear the thousands of
warnings...

These macros are needed to make sure the compiler does not optimize away
atomic constructs such as "while (!READ_ONCE(foo))" loops that do not
modify foo within the loop
Also move the barrier() define where it belongs while we are here, it is
needed for READ_ONCE/WRITE_ONCE and including ihk/cpu.h here causes
include loops
